DOOR-OPERATING DEVICE.

Application filed July 6, 1911. Serial No; 537,201.

To all whom it 'may'concer'n: 4

Be it known that I, DONALD S- Barrows,

Passaic county, New and being a citizen of the United States, have invented certain new and useful Improvements in Door-Operating Devices, of which the following is a full, clear, and exactdescription, such as will enable Others skilled in the art towhich it appertains to make and to use the same, reference being bad to the accompanying drawings, which illustrate the preferred form of the invention, though it is to be understood that the invention is 'not limited to the exact details of construction shown and described, as it is obvious that Jersey,

various modifications thereof will occur to persons skilled in the art.

' section In said drawings: Figure 1 is a transverse sectional View of a car illustrating the in vention, the section being taken on line 1-1 of Fig. 2 looking'in the direction indicated. by the arrow. Fig. 2- is a plan View of a fragment of a car, showing the invention applied with portions of the view shown in taken on the line 2-2 of Fig. 3. Fig. 3 is a section taken on line 3 -3 of Fig. 1. Fig. 4 is a vertical sectional view through portion of a cross bearer illustrating a slightly modified form of retaining means for a rack bar employed in the device.

The object of'the invent-ion is to provide means for opening and for closing and locking in closed positionlhe doors of what are commonly known as general cars, that is cars having flat bottom lportions, comprised wholly or partly of doors which are adapted to be dropped or opened to discharge the lading.

While any suitable means may be provided for operating the principal operating shaft,-I have shown no means in the drawngs as various devices are common'in the art for that purpose.

The principal object of this invention is to provide means which will permit opening and closing the doors with a-1nimi1num Specification of Letters Patent.

service I power and which will provide the means for positively locking the doors in closed position.

Referring to the parts, F is the operating shaft extending substantially the length of the car, which shaft is supported in cross Patented oer. as. rare.

' bearers or diaphragms H, while doors are with the connected by suitable hinges 1, center sills B and which doors extend outwardly as shown in thedrawing, to slightly beyond the side plate-girder B. A sill cover plate S is provided where two center sills are used, though said cover plate may be omitted in case the car is constructed with a single center sill.

Connected to the operating shaft F at suitable intervals there are pinions 1 and meshing with these pinions are racks 2 best shown'in Fig. 1, which racks travel in engagement with rollers a held on pins 6 in guide plates 3 which swivel on the shaft F. The guides 3 may comprise each a single plate as illustrated in Figs. *1, 2 and 3 or they may comprise each a pair of plates dis posed upon shown in Fig. 1.

Connected to the outer end of each of the racks-2 is a bell crank lever 4 which is mounted on a pivot 5, supported in a suitable'bearing 6, which bearing is connected with the diaphragm.

The shorter arm of the bell crank 4 is'connected with the rack 2 while its longer arm extends, when the door is in closed'position, relatively vertically as shown in full lines in Fig. 1 and carries at its upper end a suitable roller 7 adapted to bear against the lower face of the doors G, the roller 7 being carried on a laterally projecting extension of the bell crank 1 as best shown in Fig. 3.

Connected with each transverse edge of opposite sides of the pinion 1 as illustrated in the modified structure g the doors G is an angle guide bracket '8.

against whichtheroller 7 bears during the operation of opening the doors.

As each edge of each of the doors G is equipped with, the same locking means in proximity to the transverse diaphragms of the car under frame description of one will answer, for all Assuming the doors to he in closed position as shown by full lines in Fig. 1 and it is desired to open the door, the operating shaft F is rotated in clock-wisedirection carrying with it, the pinion 1 and projecting the rack 2' outwardly, that is away from the center sill,,as shown by dotted lines'in said Fig. 1, thereby rocking the bell crank lever 4 upon its pivot, carrying the lower end of the shorter arm forward and outwardiy as shown by dotted lines in said: 1 thus causing the longer. arm of said bell crank lever to be thrown inwardly and. down- ,u'ardly in the direction indicated by the arrow in Figglto the position shown in dot;

ted lines in said figure.

During this moyement the bearagainst the angle bracket-'8 which is secured to the depending flange 10 of the'door and cause said door to travel to th'e posi tion shown in dotted-lines. in said Fig. 1 to open position in which position the roller 7 willbear against the angles 1.0, which form the side edge port-ions of the door, and support the door in open position.

When it isdesired to close the as the.

' shaft F is rotated in contra-clockwisedirec tion, thereby carryingthe rack 2 inwardly and upwardly to positions=shownjin full.

lines in said Fig.1, rocking the bell crank lever/l upon itspivot, causing the rollers 7 -to bear against angles 10 011 the door and lifting the door to its upper or closed position. w

As it is necessary to lock the doors in closed position'ther'e are provided angles X near the outer ends of the angle guide brackets 8,'which serve asstops to prevent excessive outward thrust of the upper angular extensions of the arms 4t of the bell crank and prevent their passage. beyond the, outer ends of the said brackets. These angles X are riveted to the door angles or door flanges as shown at X in Figs. 1 and 2 andserve in effect as supplemental locking means forthe door lifting bell crank when the rack 2 thrusts the upper end 4 to its outermost position.
